How to change the date format using AngularJS ?

In this article, we will see how to change the date format using AngularJS. AngularJS provides 2 different ways to change the format of the date. It can be achieved by the following approaches:

• Using HTML Template Binding
• Using JavaScript Controller

HTML Template Binding: In this method, we use the pipe (|) operator. This pipe operator helps to convert a date object or number as per the required format (this includes - angular standard format and user-defined format). In angular, date objects can be modified based on any format, locale, and timezone using this operator. It formats a date in a readable format only.

Syntax: 

{{ dateVariable | date [ : format [ : timezone [ : locale ] ] ] }}

Attribute Values:

• Format: Both the predefined, as well as user-defined formats, can be used in this attribute. The default value of this parameter is -‘mediumDate’. It is an optional parameter.
• TimeZone: The default value of timezone is the user’s local system timezone. We can provide value as an offset (‘0530’) or standard UTC/GMT (IST) or continental US timezone abbreviation. It is an optional parameter.
• Locale: The default value for a locale is -‘undefined’. For example, we can set it as – ‘en_US’. It is an optional parameter.

Example 1: In this example, we are changing the current date into different formats. This date format includes the standard as well as user-defined formats. 

When we run the code, it will provide the current date in different formats.

Input Current Date: 24th March 2020

Output:

Formatted Date with default parameters: Mar 24, 2020 
Formatted Date with standard filter (ShortDate): 3/24/20
Formatted Date with standard filter (FullDate): Tuesday, March 24, 2020
Formatted date with user defined format:today is March 24, 2020

As we have seen that it is pretty easy to work with this pipe operator. Now, we will take a look at the second approach.

Using JavaScript Controller: This approach is helpful if you have a date in string format. 

Syntax: 

$scope.dateVariable = $filter('date')("dateString", "dateformat");

Example 2: Here, we are using an angular controller to change the date format. The date is passed as a string & by using the $filter filter, which is used to filter the object elements and array. It provides you the subset of an original array in the specified format. 

Output:

Input Date in String Format: "2013-07-20T18:30:00.000Z"
Output Date : 21/07/13
